Description.

Female body length: 3.31 mm (n=1). Color of head: dark brown to black. Central keel of frons: present, extending onto interantennal process. Sculpture of medial frons in female: smooth. Number of mandibular teeth: three. Basal node on mandible: present. Sculpture of frons below median ocellus: finely punctate throughout, dorsoventrally strigose laterally. Sculpture of posterior vertex: concentrically rugose. Occipital rim: comprised of medium to large sized cells. Sculpture of gena: coarsely striate. Basiconic sensillum on A7: absent.

Color of mesosoma in female: dark brown to black. Sculpture along posterior pronotal sulcus: striate, striae well defined. Notaulus: percurrent, reaching suprahumeral sulcus as a smooth furrow. Sculpture of medial mesoscutum: moderately punctate in posterior half, becoming denser anteriorly. Sculpture of mesoscutellum: smooth medially, sparsely punctate laterally. Postacetabular sulcus: comprised of small cells. Mesopleural carina: present. Sculpture along ventral half of prespecular sulcus: punctate rugose. Sculpture of posterolateral mesepisternum: smooth. Sculpture of ventral surface of mesepisternum: smooth. Setation of ventral metapleural area: absent. Setation of metapleural triangle: sparse. Sculpture of metapleural triangle: rugulose. Posterior margin of metapleuron below propodeal spiracle: straight to moderately convex. Color of legs: coxae and trochanters yellow, otherwise brown, becoming paler distally.

Color of metasoma in female: dark brown to black throughout. Posterior margin of transverse sulcus on T2: strongly convex. Sublateral tergal carina on T2: absent. Microsculpture on T2: absent. Microsculpture on T3: absent. Microsculpture on T4: absent. Horn on T1 in female: present as a large, apically rounded protuberance. Macrosculpture of T2 in female: longitudinally striate throughout. Macrosculpture of medial T3 in female: weakly longitudinally striate. Macrosculpture of lateral T3 in female: longitudinally striate. Macrosculpture of medial T4 in female: absent. Macrosculpture of lateral T4 in female: punctate rugulose. Punctation of T4 in female: absent along midline, otherwise sparse. Macrosculpture of T5 in female: punctate rugulose laterally. Punctation of T5 in female: sparse in medial third, moderately dense laterally. Shape of T5 in female: width of posterior margin greater than or equal to length. Microscupture on T6 in female: absent. Sculpture of T6 in female: smooth with sparse moderate sized punctures. Sculpture of S2: longitudinally striate anteromedially, otherwise smooth. Prominent longitudinal median carina on S2: absent.

Wings: macropterous, apex or forewing extending beyond posterior margin of T3. Color of forewing in female: slightly infuscate throughout. Color of hind wing: slightly infuscate throughout. Density of setation in fore wing: uniform throughout. Density of setation in hind wing: uniform throughout. Length of R1: more than 1.5 times as long as r. M+Cu and RS+M in forewing: nebulous.

Diagnosis.

This species has large concentric rugae along the posterior vertex similar to Trichoteleia irwini and Trichoteleia albidipes . It differs from them in that the rugae are less uniform and the head is transverse in dorsal view. Trichoteleia ketrona also does not have microsculpture on the metasoma (Fig. 155), and the anterior mesoscutum is strongly arched in lateral view (Fig. 151).

Etymology.

The word ketrona, meaning “wrinkled” in Malagasy, refers to the rugae on the posterior vertex in this species. The epithet is to be treated as a noun in apposition.
